IMPROVEMENT IN GAGE-LATHES.

Specification forming part of Letters Patent No. 17 1,696.. dated January 4, 1876 application filed July 2, 1875.

To all 'whom it may concern:

Be it known that I, JOHN M. PARKER, of South Manchester, in the county of Hartford and State of Connecticut, have invented an Improvement in Gage-Lathes, of which the following is a specification, reference being had to the accompanying drawings, where- Figure l is a top view. Fig. 2 is a bottom view. Fig. 3 is a front View. Fig. 4 is a rear view. Fig. 5 is a right-end view. Fig. 6 is a left-end view. Fig. 7 is a detail view, showing the bottom or under side of the slide y, hereinafter specified and described. y

The invention is a machine for automatically making wooden spools, such as thread is wound upon for sale in the stores. The wood is prepared by cutting into strips of proper size, square or rectangular in crosssection-though the shape in section is not essential-and this machine takes the stock in this shape and delivers it in iinished spools.

I shall describe the -parts and their operation, in the main, together.

The letter a/denotes the frame b, the power-shaft, which receives motion by a belt running upon. the pulley c in the direction indicated by the overlying arrow, and the pinion d on this shaft gives-Y motion to the gear c, which is loose on the main shaft f, which is thrown into or out of gear with thegear c by means of the clutch g, which is operated by the hand-lever hf, on which main shaft is the cam i, which, at the proper time, pushes up the vertical jaw j, which moves in the stationary pillar'l, its return movement given by the spring l, from the rear of which jaw j `ezt- 1 tends the arm m, pressed upon by the spring pillar s-theV spring t, arm u, pitman o, and4 pivoted jaw w but this set of jaws feeds the.

rough stuft', and has a back-'and-forth sliding movement, as follows: The pillar s is set on the slide y, moving back and forth in ways inl the frame or table, such movement being, given by the cam z on shaft f into the cam- .i

slot, of which the pin al projects from the bottom of the slide y. The length of movement of the slide y is adjusted for feeding different lengths for different lengths of spools, as follows: The block b1, from which the pin al immediately proceeds, has some longitudinal* .play in, and independent of, the slide y, and

the position of this block, relatively to the slide y, can be so adjusted by means of the screw c1 bearing the worm-gear d1 and the Worm-shaft c1, that the slide y, and consequently' the pillar s, shall have the desiredA notes the cam, o1 the vertical jaw, p1 the sliding pillar, r1 the spring, s1 the rearward-extending arm, t1 the pitman, and u1 the pivoted jaw.

The letter @l denotes what is known in spoolmaking machines as the rougher,77 from the.

fact that it roughly rounds the square stuff. It is hollow; has an inwardly-edged chisel or chisels; is set on the hollow shaft w1, and is rotated by a belt running on the pulley y1, in the direction indicated by the overlying arrow. The letter zldenotes a saw, for severing the roughly-rounded stuii' into spool-lengths` as it comes from the rougher. This saw is hung in the swinging arm a2.` Its forward and back movementsgiven at the proper time by the cam b2, into the cam-slot ot' which projects a pin from the reciprocating block c2, connected to the saw-arm a2' through the medium of the rod d2, adjusting-lever cz, pitman 'runninginto itscam-slot .from the block,vand

the block communicates longitudinal mot yn to the auger-bib Shaft, through the agenc'`rl 'f *the Pitman "'27 adjustinglever .027 and 'Spring pfbearing against a shoulder` on the augerbit` shafathe lpurpose of the interposition of`` this spring being to not force the auger-bit forward with too much violence when it meets a knot or other obstruction. The movement of the auger-bit, `to accommodate different lengths ofspools, is regulated by means of` are pivoted on `pinsprojecting from `the sides,`

of "the fulcrum-block u2, which is borne between two collars on the screw-rod 1:2, which screws into the fulcrum-post r2, and by rotatin g` this screw the fnlcrum can be adjusted towardl or fromthefulcrum-post. Such adjust-` ment is necessary in alteringthe length of play of a the parts i immediately affected. As the spool-blanks are severed by the saw z,

which is driven by a belt running on the pulleyjwz, they fall into the trough y, and roll toward the front of themachine, and reaching the front end of the trough fall down,one by one, upon the feeder zz, which is reciprocated forward and back at appropriate times by the eccentrica3, communicating with the feeder through therod 113, lever c3, rock-shaft d3, and arm e3, the feeder sliding in the waysf, The feeder-top f i is adjustable vertically toilit differentdiameters of spool-blanks by means of the screw g3, the top and bottom of the feede` `j' being kept apart by the springs k3, which al low the feeder to grasp the spool-blank under some pressure.

The pivoted gate ikeeps the spool-blanks from escaping accidentally at the front, it being pressed to vertical position by spring ja, and 'this spring allowsthe gate to 4give way to thefront when the feeder moves forward with `a spool-blank. This feeder takes the spoolblanks, one by one, and delivers them to the turning apparatus, which is composed in the main of the stationary rotating shaft k3, driven by belt in pulley Z3, the sliding non-rotating shaft mand chiselapparatus, shortly to `be described. The ends of the two shafts k3 mit into the ends of the central hole in `the spool-blank, the formerhaving small lugs `to cause-the blank to rotate withi the shaft` The shaft m3 reciprocates automatically to receiveand release the spool-blanks, its movelments being given by the cam` n3,\block o3, bearing-pin p3, pitman r3, adjusting-lever s3, (for different lengths of spools,) and bent pita, man t3. lThe end corners of` the spools `are a chamfered by the chisels .uin thecommon manner, and the turning of the other parts is done by chisels set in the reciprocatingchiselrest 'v3 in fthe common manner 5; but I` operate this chisel-rest automaticallyin a new manner." a

This chisel-rest reciprocates back and fortholn the ways-block w3 at the proper times, its

Vmovements being given bythe cam b2, reciprocating block c2, pitman g3, adjusting-lever z3, (for different diameters of spools,) and the` pitman a4; which takes hold upon the pivotshaft b4,-m`ade long, as shown, to permit the sidewise adjustment of the chisel-rest and the Vways-block which carries it, this ways-block having such sidewise adjustment upon the` ways-block c", the pins d4 d4 keeping the pit-l man a* always in proper line. The sidewise adjustment of the chisel-rest and the waysblock w3 is given by'means of the'adjustingscrew e4. The hook f4, attached to the shaftI 'm3, pulls the finished spool off the endof the..

shaft k3 when the spool is finished, and the shaft nts-moves back, and then the spool falls?.

down out ofthe way.

The operation ofA the parts is as follows:` The square stud' is run` through` the `rougher v1, `being fed'by thesecond set of feeding. jaws r lw, rthe jaws j o holding the stuff stationary, while the jaws r fw are retreating.A The' stuff comes out at the opposite end of the hol-` low rougher-shaft 'w1 rounded.L Here thethirdf set of feeding jaws o1 u1` feeds thestu for the saw-and auger-biathe-fourth;setof jaws,- g1 m1, holding the stuff when the jaws o1 u1 are retreating. Now, the auger-bit i bores the-` central hole, the saw zl swings forward and cuts olf a spool-blank, whichfalls into` the" trough y2, runs `down tothe front end of the]` trough, and fallson the feeder z2, whichadw ,vances and gives `the blank tothe turning-J` from the roughed stuff, the hooked lever a5,

pivoted by its rear end- `to `the leverbfVWhichr is pivoted at its foot and caused to swing in" proper times by pivoting `to the pitman f2, the.` movements of which have been described, and` said hooked lever aPbeing pressed-down by spring c5, moves "rearward at the propertime, its hook takes hold upon thefreshly-severedf `spool-blank and pulls it forwardf into the? trough y2.
